SPECIFICATION forming part of Letters Patent N0.351,6'77, dated October26,1886.

Application filed August 5, 1886. Serial No. 210,086. (No model.)

T 0 all whom, it may concern.-

Be it known that I, THEODORE B. WILCOX, a citizen of the United States,residing at Newark, in the county of Essex and State of New Jersey, haveinvented new and useful Improvements in Vaporizers, of which thefollowing-is a specification.

My invention relates to improvements in inhalers or vaporizers havingopenings at both ends; and it consists in the combination, with twostoppers fitted to the openings, of a connecting-shankbetween saidstoppers, so that the stoppers are simultaneously caused to open orclose their respective openings. The shank is made of two connectedsections with an interposed spring, so as to permit each stopper to betightly inserted or pressed into its opening, regardless of differencesin wear, all of which is more fully pointed out in the followingspecification and claims, and illustrated in the accompanying drawings,in which Figure 1 represents a vertical central section of a vaporizerprovided with my improved stopper. Fig. 2 is a horizontal section of thesame in the plane 00 .r, Fig. 1. Fig. 8 is a sectional elevation, on alarger scale than the preceding figures, of the stopper detached. Fig. 4is a vertical central section of a vaporizer provided with a modifiedform of the stopper. Fig. 5 is a similar section of a vaporizer having aremovable bottom. Fig. 6 shows a side view of the bottom detached andthe key for removing the same.

Similar letters indicate corresponding parts.

In the drawings," the letter A designates the cylindrical body or shellof the vaporizer, which is enlarged at one end to form a circulareye-cap, a. A bottom or partition, A closes the end of the shell at thebottom of the eyecap, in which partition is a central opening, B. Theother end of the shell iscontracted and has an opening, B, by which airmay enter the shell. \Vithin the shell is secured a cylinder ofperforated sheet metal or wireganze, c, which leaves an unobstructedpassage or chamber, 0, and forms an annular space between the cylinderand the shell of .snfficient size to contain an absorbent packany partof the body stimulate the nerves and blood-vessels and produce abeneficial result. The openings in the shell A register with the chamber0, and are closed when the vaporizer is notin use by stoppers E F, onefor each opening. In the bottom or partition I) of the shell is formedan internal screw-thread,

that when the stopper E is unscrewed the stopper F is simultaneouslyremoved from its seat, and finally both stoppers can be removed from thechamber 0 when the vaporizer is to be applied, and air can freely enterthe chamber. To provide for any unequal wear of the stoppers,which mightcause one stopper to fit tightly to its seat before the otherwas downonits seat, I form the shank G in sections, as best shown in Fig. 1. Theone section, 9, is formed witha socket, into which extends part of theother section, and a pin, 71, thereof enters a slot, h, in the section9. A spring, H, is placed within the socket, and'is compressed by thesection 9, thereby holding the stopper F against its seat. Thisarrangement allows the stopper E to be screwed upon'its seat regardlessof the stopper F, and consequently both stoppers always effectuallyclose the openings B B.

In the example shown in the drawings the stopper F consists of a washer,f, and a cap, f, the washer being held to an enlarged portion of theshank-section g by said cap. The stopper E consists of a threaded bodyhaving a flanged portion and a washer, c, which closes against thepartition I; of the shell A, thereby forming a tight joint. The stopperF may, however, consist of a cone properly ground, as shown in Fig. 4,or the stoppers may have such other construction as will render thembest adapted for their purpose.

To facilitate the removal of the absorbent packing and the substitutionof new material, I provide a removable bottom or partition, 12*, whichhas a screw-thread that engages an internal thread in the shell A. Awasher, b,

roo

abuts against a; seat in the casing and makes I interposed between thesaid sections, subst-au a tight joint. In this bottom is formed aninternal thread for the reception of the stopper, as before, and twosockets, jj, are also therein, into which pins on a key, J, can be inserted, so as to remove or insert the said bottom. The perforatedcylinder 0 is best secured at one of its ends to the removable bottom,so that as the latter is removed the cylinder is withdrawn from thecase, and thus the packing can be readily removed.

I do not broadly claim herein an outer and interior cylinder havingabsorbent material interposed between them, with openings andcorresponding stoppers at each end, as such forms the subject-matter ofan application filed by me May 25, 1885, Serial No. 166,681.

Vhat I claim as new, and desire to secure by Letters Patent, is-- 1. Ina vaporizer, the combination of a shell, A, an internal cylinder, anabsorbent packing surrounding the cylinder, openings in the shellregistering with the cylinder, stoppers fitted to said openings, and aconnection between said stoppers for simultaneously moving both stoppersto open or close their respective openings, substantially as shown anddescribed.

2. In a vaporizer, the combination of a shell, A, an internal cylinder,an absorbent packing surrounding the cylinder, openings in the shellregistering with the cylinder, stoppers E F, controlling said openings,and a sectional shank connecting the stoppers, substantially as shownand described.

3. The combination, with an atomizer comprising a shell, A, having endopenings, B B, and an internal cylinder, 0, of the two end stoppers, Eand F, a connecting-shank composed of two sections, y, and a spring, H,

tially as described.

4. The combination, with an atomizer com prising a shell, A, having endopenings, B B, and'an internal cylinder, 0, of the two stoppers E and F,a connecting-shank composed of two sections, 9 9, one having a socketinto which the other extends, a spring, H, located in the socketedsection, and a pin-and-slot connection between said sections,substantially as described.

The combination, with an atomizer comprising a shell, A, having a. topopening, B, an internal cylinder, 0, a removable and replaceable bottom,b for the shell, having a central opening, B, two stoppers, E and F,adapted to the said top opening, B, and the opening in the removable andreplaceable bottom, and a shank connecting the stoppers forsimultaneously opening and closing both stoppers, substantially asdescribed.

6. In a vaporizer, the combination ofa shell, A, having an opening atone end, an internal perforated cylinder, an absorbent packingsurrounding the cylinder, a removable bottom for the shell, a threadedopening in said bot-- tom, and two stoppers, E and F, connected by ashank for operating both stoppers to open and close both said openings,one stopper having a thread engaging the thread in the bottom of theshell, substantially as shown and described.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesscs.

THEODORE B. XVILCOXI.
